Morn Trars.—Referring to the remarks made by Mr. H. 
King (Entom. 139)—Is not the reason of his not catching 
anything due to the moths flying to the larger light of the 
windows which were close by ? A very good example of the same 
occurrence was told me by an old lighthouse-keeper of Hunstanton, 
a small village near Lynn, who says that thirty years ago so many 
moths, chiefly Plusia gamma, came round his light on dark nights 
that he was obliged to beat them away with a heavy stick; but 
since a new village has sprung up close to the lighthouse, and at 
the present time hardly any fly to the light. This seems to be 
because they are more attracted by the numerous, though not so 
strong, lights of the village, than by the single light of the light- 
house.—K. M. Betog, jun.; King’s Lynn, Norfolk. [Possibly 
our correspondent has offered, in his suggestion, the right solution 
of the failure of many who have tried the moth trap without 
success.—ED. | 
Moru Traps.—From divers remarks made in the ‘ Entomo- 
logist’ on this subject, two things are essential to the trap being 
a success,—the first, and most important, being a suitable night ; 
and the second, an extensive and uninterrupted view. The first 
may be easily remedied by trying the trap every night, so as to 
be prepared when the suitable evening does arrive; but without 
possessing the second it seems hardly worth the trouble to remedy 
the first. I should here like to ask those of your readers, who 
use Dr. Knagg’s moth trap, or modifications of it, if the moths 
will remain therein till morning when captured; or if it is 
necessary to get up two or three times in the night to see if any 
moths have been captured, and if so, to box them? The advantage 
of Mr. Sabine’s trap (Entom. 138) is that it is next to impossible 
for the moths to get out when they have entered it; whereas in 
that of Dr. Knage’s the ingress and egress appear to be equally 
easy.—A. E. Hatt; Norbury, Pittsmoor, Sheffield. 
Rearinec Larva.—For some time I have adopted the plan 
advocated by Mr. Seymour St. John (Entom. 164), but with a 
little variation. As this may be of interest to some of your 
readers, I will, with your permission, explain my method. In 
the place of bell-glasses, which are rather costly, I purchase the
